I am very confused by the lack of trace output for the bios execution. That
should have worked. It's clearly running the tables...

[    1.960340] nouveau 0000:01:00.0: devinit: running init tables

Secondly, one of your bios init scripts contains the command

0x8209: 7a 54 b1 13 00 02 00 00 00                     ZM_REG   R[0x13b154]=
 =3D
0x00000002

in init script 3 (starting at 0x8116). This is the cause of

[    4.108908] nouveau 0000:01:00.0: bus: MMIO write of 00000002 FAULT at
13b154 [ IBUS ]

However that is only reported when GT214_DISP is being initialized. Again, =
odd,
but I'm not 100% sure how the init scripts are executed. This might have to=
 be
one for Ben...
